Condensing gas rooftop unit (C-RTU) installation is very similar to the installation of conventional gas RTUs. However, C-RTUs require careful attention to condensate management, including specific approaches to piping, pumps, neutralizers, and freeze prevention. Properly managed condensate will ensure efficient C-RTU operation without the risk of disruption, damage or code non-compliance.

This guide references code requirements, manufacturer instructions and practical experience to provides tips and best practices for installing C-RTUs.
